Gems FS-600 Series Operating And Installation Instructions

Prior to installation, confirm system versus sensor specifications and media compatibility of the sensor. Water hammer
effects should be minimized to prevent potential damage to the unit. Sensor can be mounted in any horizontal, vertical
or skewed orientation; however a fully filled flow body is required for accurate sensing. Correctly installed, the sensor
works maintenance free.

Installation

Apply a sparse amount of thread sealant (Permatex "No More Leaks"®) or Teflon® tape to the male threads intended
for installation. Ensure that the sealant does not enter into the sensor flow area. Hand-tighten the unit in place.
Tighten in additional 1/4 turn increments until a seal is achieved. Do not exceed one and one-half additional turns total.
